Hardest AS Maths modules to get an A in?Watch this thread
Out of the ones you have listed, I would say M1.
S1 - pretty easy to get an A in if you know all the formulae.
C2 - harder than C1 but doable. Bloody trig identities.
D1 - very easy to make mistakes. Everyone I know who's done this has either got a high A or an E.
M1 - tougher than S1.
I'd say D1 is the hardest module in A level maths, hands down (not counting further maths of course). It's completely different from all the rest. It's not impossibly difficult, but core maths (C1 to 4) is a joke compared to decision maths. I didn't like the style of the D1 paper.
m1 is sooooooooo hard; espicially if you dont understand it
Sometimes I question is it even maths?
(but BAM June 2014 paper had maths in it)
M1 has more "algebra" but its a pain in the ass compared to S1. The only thing hard in S1 is the probability stuff.
